Review: Decent upgrade - Works as expected, a nice small power boost without adding too much draw to the prime making it still easy to do one-handed.
Review: Not bad. - Pretty good for a lower-level spring replacement. Got this to put in an Alpha Trooper instead of a Retaliator and it hits around as hard as my stock X-Shot Longshot, so it's not a 200fps menace of a blaster but it's still a blast for humans versus zombies. Helps it's also super-easy to install since it's not meant to pre-compress.
